Pumpkin seeds, also known as pepitas, nestle in the core of the pumpkin encased in a white-yellow husk. These super seeds contain a number of minerals, such as zinc, magnesium, manganese, iron, copper, and phosphorus, along with proteins, monounsaturated fat, and the omega-3 and omega-6 fatty acids—all of which aid the brain in different ways. They also contain the amino acid glutamate, which helps the brain produce the antianxiety chemical GABA (gamma-aminobutyric acid). Pumpkin seeds help improve memory and focus. You can use pumpkin seeds as a garnish, add them to granola, or roast them and eat them by the handful. If you’re not a huge fan of the seeds, pumpkin seed oil has many similar benefits.
